The benefits to human health are mainly reflected in the following four aspects: 1 treatment-because the food eaten by urbanites is too fine and the crude fiber is insufficient, and white-collar women are under great work pressure and lack of exercise, constipation patients are increasing day by day. Dry stool on the intestinal wall reduces intestinal mucus secretion, affects normal peristalsis and aggravates constipation. In addition, because the intestine absorbs too much toxins, other organs will also be affected. Some girls' bad breath is caused by harmful gases discharged from the respiratory tract. Hydrotherapy can reduce the generation and discharge of harmful gases in the intestine, such as hydrogen sulfide, ammonia and biogas. 2 cancer prevention-food residues will produce some carcinogens after fermentation and long-term corruption in the large intestine. Because the meat stays in the digestive tract for too long, the contact time between the large intestine and carcinogens will be prolonged accordingly. In order to prevent the occurrence of colorectal cancer, it is necessary to clean the large intestine frequently. 3 beauty-capillaries and a large number of glands under the skin excrete metabolic substances and some harmful substances in the blood. In the process of excretion, the skin is damaged, which leads to skin problems such as acne and pigmentation. Intestinal hydrotherapy increases the chances of harmful substances being discharged from the intestine and reduces the chances of harmful substances being discharged through the skin, which is of course beneficial to skin health. 4 health care-some harmful substances in the blood are detoxified through the liver, which consumes the liver detoxification enzyme system. After acting on the brain, people will feel tired, which will have an impact on the immune system and human metabolism. Hydrotherapy can remove harmful substances and has a health care effect on the whole body.
